NTN UC319 Insert Bearing 95x200x51mm

The NTN UC319 is a new insert bearing manufactured by NTN. It measures 95mm by 200mm by 51mm and carries the model number UC319. This component is designed for use in electrician tools and related power-tool applications where a precision bearing of this size is required.

Maintenance teams replacing worn bearings

Technicians servicing electrician tools that specify a UC319 insert bearing will find this part a direct fit. It is not suitable for applications requiring different bore diameters, outer diameters or widths, nor for tools that call for a different bearing series or sealing arrangement.

95mm bore 200mm outer diameter 51mm width

The critical specification is the 95mm bore, 200mm outer diameter and 51mm width, identified as model UC319. Confirm these three dimensions against your equipment manual before ordering to ensure the bearing matches the housing and shaft exactly.

Questions about this item

What shaft diameter does the UC319 bearing's 95 mm bore require?

The 95 mm bore fits a shaft of that exact diameter, so the buyer must already have a 95 mm shaft or an adapter sleeve to match.

Will the 200 mm outer diameter clear the housing on my existing equipment?

The 200 mm outside diameter needs a housing bore of the same size; measure the current housing to confirm the UC319 will seat without interference.

How can I verify the 51 mm width is seated correctly after installation?

After pressing the bearing in, measure the installed width — it should read 51 mm — and rotate the shaft to feel for smooth, consistent motion without binding.
